SPECIFICATION forming part of Letters Patent No. 648,674, dated May 1, 1900. Application filed lJanuary 3, 1900. Serial No. 204. (No modell) To all wig/bm, zb may concern:

Bel it known that I, JOHN A. SnEiniAN, of Worcester, in the county of lVoi-cester and State of Massachusetts, have invented a new and useful Improvement in Folding-Box Mechanisms for lnvelop-liiacliines,-of which the following is a specification. I

. My invention relates especially to that class of foldingbox in which the bottom of the box is stationary. 'lhe means generally provided lfor removing the envelop from such a foldingboxis a forked mechanism which moves upward through slots in the bottom of the box and lifts the envelop'ont of the box. This usually necessitates the. providing of some moving mechanismflocated above the box which shall receive the envelop from'the forks and place itin the drier.

My invention consists in a folding-box provided with mechanism for pushing the envelop oil.' of the folding-bed in a plane parallel with its face,`so that the envelop may fall anism, showing also a portion of the drying mechanism. Fig. S is a vertical sectionon line 3 of Fig. 2, and Fig. 4 is an enlarged View in perspective of the back-flapfolder."

.lt will be noted that portions of Figs. l and 3 are taken upon vthe saine section-line, and the pushing mechanism for removing the en.- vclop is shown in Fig. 1 in its outer position and in Fig. 3 in its inncrposition.

A is the table, suitably supported dinary manner upon frames B. Upon this table is mounted the stationary bed C of the folding-bex. About this bed are mounted the fonr folders l) E F G, each ofthese folders being j ournaled in suitable bearings carried by the table A in the usual manner and being given the ordinary oscillating movement, such as is customary in envelop-maf;

chinos. by. means el suitable cams on the camshaft ll, the rods connecting thei'olders with the cams or cam-levers being lettered-D', E', F, and G', respectively. usual construction, except that its shaft f' is provided with slots f of. such size and so located that when the folder is in a vertical position the pusher-arms J, the forward ends of which lie in said slots, may move forward through the slots and on being Withdrawn again into their rearward position will not interfere with the free oscillation of the folder F.

The pusher J, which constitutes the main novelty of my present invention, is preferably made with two arms .T J, as'shown, which project from a cross-bar K, carried by av Slidell, suitably mounted in ways M, supported upon and extending from the table A.

Motion is given to the slide L andj pushers v .l in the following manner: From the under side of the table A projects a bracket A', in which is mounted a stud A2, which carries a rockin g sleeve c, havin g two rocker-arms,one, Z, p rojectingupward and connected by alink -Z' with a slide L, andthe other, h, projecting outward and connected by means of a con- 'lhe folder F is of v neeting-rod h' with the cani-lever h2, pivoted at B to the frame l. The cam-lever h2 carries a cam-roll h3, engaging with the cam ll' and held against the spring h".

The folder is of that class of folders which while it is suitably jonrnaled at each end and is provid-ed .with a suitable bead by cam'by means of the ing position, is cut away underneath, as will.

be seen from Figs. l and 3 so as to provide ample space for the envelop to be pushed under it when the folder is in its open position.

' I have shown portion of a drier N, located below an opening in the table A and in position rfu to receive the envelop as it 1s pushed from the folding-bed, n n being the fingers of the device, andv n' a supporting-roll on which it turns. Suitable means may be pro\-'idcd-.-forI velop into the drier after it leaves the foldingbox, the shield P being located in the path of its under side to the drier."

The operation of my invention will be understood by all skilled in the art.l The en- Velop having been gummed by mechanism suitable for the purpose is brought by suitable means under the plunger, which is indicated in dotted lines at Q and which descends at such time as the folders are open-thatis, in the position shown in the drawings-aud drives the blank down into the folding-box and against the bed vC thereof. The folders then close successively, the two end folders closinglfxrst, if the envelop be of the ordinary character, the back-flap folder F folding next, and, last of all, the seal-Hap folder, which, having but a narrow edge or bead d, simply turns the ap down without causing it to ap- 1proach thebody of the envelop so nearly as to stick. The envelop havngthus been folded in the usual` manner the folders openagain, thus opening thepassage through the slots f for Vthe pusher -arms and under the folder D for the envelop, and the pusher-arms, which have heretofore beenin the position shown in Fig. l, with their front ends just in the rear of the axis of the folder F, are pushed forwardinto the position shown in Fig. 3, passing through the slots f in the shaft of the folder F. This drives the envelop out', as is 'Y indicated in dotted lines in'Fig. 3, under the folder D, against the guide P, whichturnsits advancing edge downward, so that the" en velop falls into the drier N between the fmgers n n and into the position shown in Fig. 1. The pusher-arms are then withdrawn again into the position shown in Fig. l and the mechanism is then ready to receive another blank from the plunger Itis evident that the pushers may be oper-l ated in a different manner from that shown and may in themselves be different in construction, one arm with a broad -faeebeing used instead of two, the novelty of my invention consisting, broadly speaking, in the use of a pusher of some form to push the folded envelop od from the bed of the folding-box in a plane parallel with the plane of the bed.

'What I claim as my invention is- 1. In an envelopmachine, an envelop-folding bon,I having a solid bed, in combination with mechanism for pushing the envelop therefrom,. consisting of a reciprocating pusher movable in a plane parallel with the face of the folding-bed and in close prbximity thereto., whereby it is adapted to engage the adjacent edgeof the folded envelop and pushy it therefrom, as set forth. y

2. In combination with the bed of an en volop-folding box, a series of oscillating fold` ers and a pusher adapted to reciprocate upon vthe foldingbed and under one of said folders,

said folder being suitably shaped to allow said pusher to pass under it, as and for the purposes set forth. L.

3. In combination with the bed of an cnvelop-foldin g box', a pusher adapted to movel forward and back across the face of the bed of said box, andv means whereby it is reciprocated, the folder .in front of said pusher being cut away as described, whereby said pusher will engage one edge of the envelop and push it across the face of said bed and under said folder, as and for the purposes set forth. i

4. In an envelop-machine, a folding-box provided with a bed and four oscillating folders, in combination with a pusher adapted to reciprocate across and parallel with the face of said bed and under one of said oscillating folders, said folder being shaped to allow the passage of the pusher under it and the 0pp0s` ving folder being. suitably shaped to allow a folded -zenvelop to be pushed past it and off from the bed of the folding-box, as set forth.

5. Inan venvelop-machine, in combination with a drying mechanism, a-folding mechanism comprising a folding-bed and four reciprocating folders, and a pushing mechanism consisting of a 'reciprocating pusher of the .envelop therefrom in a plane parallel there- 1 with and engaging the adjacent edge of thc envelop, and a drying mechanism located to receive the envelop as it falls from said folding-bed, -a shield located in front of the path of motion of said envelop as it is pushed from said folding-bed and adapted to direct it downward in'to said drier, as and for thefpurposes set forth.

' 7. Incombination with the bed of a fold ing-bexaudmeans operating in close proximity thereto for engaging the adjacent edge of a folded envelop and pushing the same in a horizontal plane therefrom, a drier located to receive said envelop as it falls from said folding-bed, and means to guide the envelop by its under side into said'drier, as set forth. In testimonywhereof I have hereunto set my name this 20th day of December, 1899.
